Keep from burning wires

What way do you guys use to keep the spark plug wires from burning on the headers? Mine are really close to em, so i have to do something before i end up having to buy new wires!

Re: Keep from burning wires

asbestos jackets? good wires? I've used MSD wires and they blistered when they were just close to the headers, switched to Taylor wires and nary a problem

Re: Keep from burning wires

Shorty plugs and taylor wires.

Don't bother with the boot sleeves. The extra thick layered aluminum gaskets tend to blow out if you put any power to them. Header wrap will actually make it worse since they hold in heat and burn anything within 3/4 of an inch.(yes the wrap one sounds weird, but i actually had to cut 4 inches or wrap off due to this, but does keep anything more than an inch away cooler. odd but thats how it works)

Wheres that money tree hiding and who forgot to water it?

Re: Keep from burning wires

I use the Accel shorty plugs (make sure the part# has an "S" on the end) and on 2 of the plugs, I had to use these....( no need to buy a whole set since they sell them singularly)....

Funny you ask this question. I was just looking at this stuff from Accel.

Re: Keep from burning wires

I put a set of Taylor cut to fit wires on my 66. The second cylinder on the pass side has had the 90 deg boot in contact for the header for six months and seems just fine.

I planned to dimple the header, but my half hearted attempt did not put much of a dent in, so I left it.

What is a good short spark plug part number?

Re: Keep from burning wires

I really like those ceramic booted Accels.

What kind of looms do you use to hold em away from the pipes?

Jacobs Electronics makes those ceramic boots too. They'rse supposeed to withstand 2,000 deg. F. and they cost $200 for a set of eight. So I bought them. The problem is, that they're bigger than an ordinary sparkplug boot, and unless the headers you have provide a real lot of room, you won't even be able to fit those ceramic boots over the sparkplugs. I had to return the Jacobs ones I bought because of that bigger size. There wasn't any room to squeeze them on, so the fact that they're ceramic was worthless to me.

small block or big block?
big block- get the $17 looms from GMPP. it is the same parts that they use on all the big block crate motors.
small block- 88-99 Chev/GMC truck. they bolt to the sides of the centerbolt heads, but if you've got old perimeter bolt valve covers it's easy to bend the mo8unitng tabs 90 degrees to use the valve cover bolts. some of them have a bracket that bolts to the back of each head, too, and the looms hold the wires firm and disappear into the engine compartment.

Re: Keep from burning wires

I had the same problem with number my 3 plug wire. I run Brodix heads with raised exhaust ports, making a standard Big Block header a tight fit plug boot wise. The Cloth covers work until the first prolonged stand on it session. The only fix for me was the remove the header and dimple it in the appropriate area which is still close.
